RAILW Y-sienna Specification of Letters Patent.

Patented July 27; 1920.

' Application filed November 27, 1916. Serial No.'133,724.

To all whom it may conccrni Be it known that I, NUiWLA JQBoURGE,

a citizen of the United States, residing at Erath, in the county of Vermilion and State of Louisiana, have invented certain new and useful Improvements in Railway- Signals, of which the, following is a specification.

The present invention has reference, gen,- erally, to improvements in signals; and the invention relates, more particularly, to a novel railway signal.

The invention has for its principal object t provide a signal, whereby the approach of a train will be announced, previous toits passing a crofss-road, thereby warning pedestrians and drivers of vehicles and pre-' venting collisions and other forms of accinumber of parts arefew, the construction.

simple, the cost of productionsmall, and efliciency of operation high. I f I Other and furtherimprovements and novel details in the construction and arrangement of parts will be appreciated from the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part thereof and wherein a preferred embodiment of the invention is shown for the purpose ofillustration. i I y j In the drawingsz w Figure 1 is a fragmental .side elevation of a railway track w nal arrangedfthereon, H V

Fig. 2 is a top plan of the same, Fig. 3 is a fragmental detail-'n sideeleration ho e s h nect n: of th signa operating means with the tripping means,

and. y

Fig. 4 is a fragmental detail in top plan of oneof the trip, members. r 7 j Fig. *5 is a longitudinal section-view through one end of one of the ties, illustrat:

ing the manner in which the springnor: nially retains the head in position beside h m l' aci ta et dep ioi k ith my improved sig-.,

Fig. 6 is a detail perspective viewof a depressor head and the support thereof used in the present device. 1

. Referring now more particularly to the drawings, wherein like reference characters designate corresponding parts throughoutthe several views thereof, I have shown by way of illustration the present improvements as applied to an ordinary railway track, the rails of which areindicated by the numeral 1 and the cross ties by' the numeral 2, certain of which,-.are of greater.

width than others, the purpose of 'which will be subsequently apparent;

Referring toithe present improvements, 7

a supporting standard?) is arranged in proximity of 'one of the rails 1, the lower end thereof being suitably embedded within a foundatiom'which maybe and preferably is formed of cement or thelike, whereby the said standard will vberigidly held in position. A signal 4, in the shape of an arrow, is pivotally-supported .withinthe bifurcated upper extremity of the supporting standard 3, as at '5 andserves asv the visual indicating means; similar form of audible signal 6 is 'connected to the rear endqof thearrow 4, by

means of a link 7 and when, shifted from one position to another by the movement ofthe arrow 4, will, of cour'se,'ring, thus affording the audible signal. A weight 8 is aflixedto the rear extremity of the arrow 4 and, obviously, maintains the same normally in inoperativeposition.

"\Vith a view toward providing means whereby the arrow 4 and bell 6'will be actuated, there is formed within the wider of the cross ties 2, recesses 9fwhichhave arranged therein the lateral offset bearing portions of substantially bell cranked shape arms 10, the said lateral portions being indicated by the numeral 11'. To secure the. portions 11 withinthe recesses 9, staples or the like 12.are;.engagedtl ereover and driven into the ties upon which the arms 10 are arranged. Heads .13. are arranged upon the outer ends of the arms l0 and tion of the adj'acent rail 'llo maintain',

the heads 13in proper positionfwi rel a I h -i t ul rm 1f as arran ed ad: ia f r t metal rack t or; imple A bell. or other dfeb i tf hef de was teaehin oosition oins 17 are assed therethroiwh l 1 l a and embedded within the side walls of recessed'portions 18. A rod 19 is slidably mounted upon the cross ties'2 andhas upwardly bent portions 20 terminating inhorizontally extending portions 20 whereby the upper ends 01 the arms 10 can be engaged with the horizontally extending portion. To prevent the arms 10 from disengagingythe horizontally bent portion of" the rod 19, stop fingers 21 are formed upon the ends of portions 20.1 It-is'to be noted,

that the rod 19 is moved in but a single direction for operating the signal and, consequently, a pull must'be delivered-thereupon by one of thearms 10 when actuated, while a push'must be delivered thereupon by the remaining arm When it is actuated.- To allow the last'inentionedarm to shift the rod 19, a stop 22 is arranged uponone oftheihorizontally extending portions 20, A red 23 is'connected with the forward end of'the arrow 4, as at 24 and extends into engagement with a bell crank lever 25, which is pivotally secured to one of the cross ties,

as at 26, the'connection between the lever and'the rod being indicated by the numeral} 27. The're'maini'ng end of the lever 25 is received withina looped portion 28 formed in the sliding rod 19. Thus, movement of the said arm 19 will betransmitted to the bell crank arm and thence, through the medium of the rod 23 to the arrow at.

' The operation of the'construction maybe reviewed as follows: I v

The ofiset portions 13 of the trips 13am normally held, by means of the springs 16,

in a position above the tread surface of the rails 1. Consequently, when the wheels" of the rolling stock engage the same, the arms 10 will be oscillated and a sliding movement imparted to the rod 19, which, by reason of its indirect connection with the arrow 4 will cause that member to be moved into operative-or signaling position. During movement of the arrow to signaling position, the audible signal 6 'will be actuated.

.Hence, a dual signal will be afforded and pedestrians and'drivers of vehicles warned of the approach'of the train. When the trips are disengaged from the wheels of the rolling stock, the weight 8 as' arranged upon therea'r portion of the arrow 4: will return the said arrow to inoperative position, while the .arms of the springs 16 will return the offset portions 131totheir normal positions with relation to the rail 1 and the construetion rendered ready for a second or further operation. 7 a

It will be noted that asthe vertical arm of the lever 25 is swungin either direction it will describe an aro'about the pivotal point of the lever. This movement is allowed by the shifting of the ro'd'19, since the horizontally extendingportions and the upwardly bent portions of the rod 19 are carried by; the arms 10. By referring to Fig. 1, it will be noted that the arms 10, when in normal position, extend to one side of planes extending perpendicularly 'from the ties and for this reason as these arms are swung in either direction, their outer ends'willalso describe the arc-of a circle. greater length, the are thus described will be greater than the are described by the vertical armof the lever'25 janda's a result the Owing to their rod 19 will be lifted from the ties 2 at times and thenmoved backtowardthe ties 2, as the arms 10 are swung; (Therefore, the rod 19 will moveto accommodate the arcuate movement of the vertical arm of the lever 25, thus permitting this lever to move'to operate the pintle 4 through the rod 23.

i It is to be understood, that the sliding rod 19 may be of anyrlesired' length and of course, the trips placed at asuitable distance from the cross-over, sogas to give ample warning topersons, before the train passes the cross-over. y

' While 'I have illustrated and described with a considerable degree-of particularity,

constructional details of the device embodying my invention,'it is to b'e'understoodthat' the invention is not limitedto the particular form and arrangement of the several parts, which may be modified within a wide range without departing from the essence of the invention'the construction shown and the description based thereon being intended to be taken in an illustrative, rather than a limiting sense.
